Phys.org / Multivariate patterning of human pluripotent cells reveals induced paracrine factors in kidney organoid development
Bioengineers have shown great promise in creating complex multicellular kidney organoids (tiny, self-organized tissues) in the lab using pluripotent stem cells . They can further improve the procedure for different outcomes, ...
Phys.org / Inverse design of porous materials using artificial neural networks
The ability to generate optimized nanomaterials with artificial neural networks can significantly revolutionize the future of materials design in materials science. While scientists had progressively created small and simple ...
Phys.org / An electrically pumped surface-emitting semiconductor green laser
Scientists and Engineers have used surface-emitting semiconductor lasers in data communications, for sensing, in FaceID and within augmented reality glasses. In a new report, Yong-Ho Ra and a research team in the departments ...
Phys.org / Shrinking dinosaurs and the evolution of endothermy in birds
The evolution of endothermy (thermoregulation by metabolic means) represents a major transition in vertebrate history. However, the process of endothermy evolution and its timeline in birds and mammals remains controversial. ...

In a new report published on Scientific Reports, Milan M. Milošević and an international research team at the Zepler Institute for Photonics and Nanoelectronics, Etaphase Incorporated and the Departments of Chemistry, Physics ...
Phys.org / Wave physics as an analog recurrent neural network
Analog machine learning hardware offers a promising alternative to digital counterparts as a more energy efficient and faster platform. Wave physics based on acoustics and optics is a natural candidate to build analog processors ...
Phys.org / Intrinsic quantized anomalous Hall effect in a moiré heterostructure
The quantum anomalous Hall (QAH) effect can combine topology and magnetism to produce precisely quantized Hall resistance at zero magnetic field (an environment carefully screened from magnetic fields). In a recent report ...
Phys.org / Constructive molecular configurations for surface-defect passivation of perovskite photovoltaics
Materials scientists aim to enable surface-trap-mediated nonradiative charge recombination to engineer highly efficient metal-halide perovskite photovoltaics (solar cells). Since unproductive charge recombination at surface ...
Medical Xpress / Miniaturized, light-adaptive, wireless dosimeters autonomously monitor exposure to electromagnetic radiation
Electromagnetic radiation (EMR) exposure from the sun and artificial lighting systems represent a health risk, therefore personalized methods for EMR dosimetry can guide people toward lifestyle behaviors that ensure healthy ...
Phys.org / Nearly quantized conductance plateau of vortex mode in an iron-based superconductor
When a semiconducting nanowire is coupled to a superconductor, it can be tuned to topological quantum states thought to host localized quasiparticles known as Majorana Zero Modes (MZM). MZMs are their own antiparticles, with ...
Phys.org / New class of crosslinker-free nanofiber biomaterials from Hydra nematocyst proteins
Nematocysts are stinging organelles of cnidarians that have remarkable mechanical properties to undergo 50 percent volume changes during explosive exocytosis (process by which cells excrete waste and large molecules), while ...
Phys.org / Elastic kirigami patch for electromyographic analysis of the palm muscle during baseball pitching
Surface electromyography (sEMG) is widely used to investigate human motion including athletic performance. Baseball pitchers require very precise movements to pitch the ball to the strike zone, where the palm muscle plays ...
Phys.org / MATRIEX imaging: Simultaneously seeing neurons in action in multiple regions of the brain
Two-photon laser scanning microscopy imaging is commonly applied to study neuronal activity at cellular and subcellular resolutions in mammalian brains. Such studies are yet confined to a single functional region of the brain. ...
